Mesenchymal tumors are inherently diagnostically challenging, but a significant practice gap in their interpretation has developed as new entities and genetic abnormalities have emerged. Diagnostic challenges are associated with distinguishing benign spindle cell proliferations from high grade sarcoma due to histologic and immunohistochemical overlap. In addition to benign and malignant categories, contemporary classification of mesenchymal neoplasms emphasizes lesions with intermediate biologic potential, including those that are locally aggressive or rarely metastasize. There are circumstances in which pathologists can render only descriptive diagnoses without precise classification. New discoveries in molecular genetics have clarified some of these problematic lesions. Furthermore, there are newly described entities that practicing pathologists should be aware of so that tumors are appropriately diagnosed and optimally treated. This course, presented by expert mentors and educators, explores a comprehensive panorama of lesions and anatomic sites.
Target Audience
Practicing academic and community pathologists, and pathologists-in-training
